Check Engine Light
RE: Check Engine Light
Klute,
It might be a good idea, if some of the hoses are cracking, to change out all the hoses to the newer silicone type. It doesn't cost big money, and you can even color coordinate (?), them to the color of your choosing. Check the ones under the truck at the charcol canister and those solenoids too. Most likely, the ones that are located at the evap canister are the ones that gave you the codes.

RE: Check Engine Light
They replaced 3 hoses to/from the canister. I picked it up this AM and have not looked, but I would guess they will wear out in 4 years too.
What a joke! Rubber hoses they carry gas fumes that wear out/crack in 4 years and a cost of $384!

P0442 is EVAP system leak monitor, medium (0.40) leak detected
P0455 is EVAP system leak monitor, large leak detected

Check engine light has been on for a couple of days. I called the dealer and the want $70 to just diagnose the problem (rip off).
I went to local auto parts store and got the codes.
1) 0442
2) 0455
Now the guy at the parts store said both were related to fuel delivery. He suggested that I start with a new gas cap, and that might remedy 1 if not both problems.
Now he said the 0442 was a 'small' vacuum problem and the 0455 was a 'gross' vacuum problem. Now, I like parts guys, but some are just not the sharpest tool in the shed. He said the gross one could be a vent or a problem with the filler spout to the gas tank.
He also said that it may take several days to reset the check engine light, actually he used the word 'cycle', meaning bring the truck up to normal temps and then cooling down to reset the light/codes. This sounded weird to me, anyone have any info on this.
The device I used to get the codes had a 'reset' button on it, but he told me not to use that.
It looks like I will have to go back in a couple of days and have the code(s) dumped again if the light does not go away.
Any additional info would be greatly appreciated...
Thanks,
Klute

RE: Check Engine Light
Could have been the air filter. I read some where that some reusable Air filters, when cleaned and reoiled, some times cause havoc with the system, especially if you used to much oil, on the air filter. I read when reoiling, you should let it dry fully for a day, preferably in the outdoors, before replacing.

FYI...
3rd gen rams will kick out their own codes by turning the key to "on" 3 times without turning to "start". Just look at the digital odometer readout..it will give you a "P" code.

Great info... This will save me from going to autozone from now on.... I'm getting the P0442.... guess it's time to start checking the vacume lines.
